S62.022G Displaced fracture of middle third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with delayed healing

Name of the Condition

• Displaced fracture of middle third of navicular [scaphoid] bone of left wrist, subsequent encounter for fracture with delayed healing (ICD Code: S62.022G).

Summary

This condition involves a displaced fracture in the middle third of the scaphoid bone, a small wrist bone near the thumb base, on the left side. The fracture is classified as a subsequent encounter, indicating follow-up care after the initial injury, and is noted to have delayed healing, meaning the bone has not progressed as expected during the normal recovery timeline.

Causes

Displaced scaphoid fractures typically result from a fall onto an outstretched hand, direct wrist trauma, or severe twisting injuries. Delayed healing may occur due to factors like poor blood supply to the scaphoid, inadequate immobilization, or underlying health conditions affecting bone repair.

Risk Factors

• Participation in contact sports or high-impact activities with fall risks.
• Osteopenia, osteoporosis, or other bone-weakening conditions.
• Smoking, which impairs bone healing.
• Previous wrist injuries or fractures that compromise bone integrity.

Symptoms

• Persistent pain and tenderness at the thumb base or wrist.
• Swelling or bruising that does not resolve with time.
• Limited wrist mobility or difficulty gripping objects.
• Possible clicking or grinding sensations during movement.

Diagnosis

Diagnosis involves a physical exam to assess pain, swelling, and wrist function. Imaging, such as X-rays, CT scans, or MRIs, confirms the fracture, evaluates displacement, and assesses healing progress. Bone scans or repeat imaging may be used to detect delayed union.

Treatment Options

• Extended immobilization with a cast or splint to support healing.
• Pain management with medications or physical therapy.
• Surgical intervention, such as bone grafting or fixation, if healing does not progress.
• Monitoring with regular imaging to track bone repair.

Prognosis and Follow-Up

Healing time is often prolonged with delayed union, requiring close follow-up. Most fractures eventually heal with proper care, but some may need surgery. Long-term monitoring ensures full recovery and prevents complications like arthritis.

Complications

• Nonunion (failure to heal) requiring surgery.
• Avascular necrosis (bone death) due to poor blood supply.
• Post-traumatic arthritis in the wrist.
• Chronic pain or reduced wrist function.

Lifestyle & Prevention

• Avoid high-risk activities until fully healed.
• Use protective gear during sports or work.
• Maintain bone health with calcium and vitamin D.
• Quit smoking to improve healing outcomes.

When to Seek Professional Help

Seek care if pain worsens, swelling increases, or mobility declines. Contact a provider if numbness, tingling, or signs of infection (redness, fever) occur.

Tips for Medical Coders

Document the fracture location (middle third, left wrist), displacement, and subsequent encounter status. Note "delayed healing" to justify the code. Include details on imaging, treatment, and follow-up to support medical necessity. Ensure documentation aligns with the clinical course and healing timeline.
